HUB-ATTACHING DEVICE.

SPECIFICATION forming part of Letters Patent No, 711,888, dated October21, 1902.

Application filed August 6, 1902 T aZZ whom it may concern:

Be it known that I, IRA F. W'OOD, a citizen of the United States,residing at Galveston, in the county of Cass and State of Indiana, haveinvented certain .new and useful Improvements in Hub-Attaching Devices;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to hub-attaching devices, and has for its objectto provide ajdevice of this character by which the tapior nut may bequickly and securely applied to the axle of a vehicle and have connectedtherewith means for keeping dust and grit out of the end of the hub.

"With the above and other objects in view, which will readily appear asthe nature of the invention is better understood, said inventionconsists in certain novel features of construction and combination andarrangement of parts,which will be hereinafter fully described andclaimed, and illustrated in the accompanying drawings, in which i Figure1 is a vertical longitudinal section of a portion of a vehicle hub andaxle, showing the application of the device thereto. Fig. 2 is a sideview of the device detached. Fig. 3 is an end view of the dust-cap.

In the drawings, 1 denotes a hub, and 2 the axle or spindle, of avehicle. 3 denotes the attaching device, which consists of a tap or nut4, preferably rectangular in shape and having a smooth bore formedthrough the same for the reception of the end of the spindle 2. Theinner end of the tap or nut 4 has loosely attached thereto afrustoconicalshaped bearing-block 5, having a central bore correspondingto and in alinement with the bore of the nut 4:.

In the face of the block 5, adjacent to the inner side of the nut, isformed a circular depression forming. a seat for a coil-spring '7, whichsurrounds the axle spindle at this point. One end of said spring bearsagainst the end of the nut at and the other end against its seat in theblock 5, the tension of the same being to force the nut and block apart.The movement of the block is limited by screws 8, passing throughcountersunk holes in the block 5 and being screwed into the end of toform an annular flange.

Serial No, 118,660. (No model.)

I the nut 4, the amount of play given the block being regulated by thedistance the screws are driven into the nut.

The object of the block 5 is to continually force the washer 9 in theend of the hub up tight against the end of the box, thereby preventinglateral movement of the hub on the spindle, this construction taking upall Wear on the washer until the same is entirely worn out;

The means for holding the nut on the spindle consists in providing thenut on two of its faces'with alined holes or openings 10, which openinto the bore of said nut and are adapted to receive the angularly-bentends 12 of clamping-arms 13, which are connected together by a coiledspring l-ii engaging short lugs formed on said arms. The ends 12 of thearms 13 pass through the openings and engage an annular groove 15,formed on the axle-spindle 2, thereby holding the hut in place.

16 denotes a dust-capin the shape of a circular disk, the edge of whichis turned over This dust-cap is adapted to snugly fit within the end ofthe ferrule on the hub to keep out dust and dirt.

17 denotes slots formed in the disk 16, which are'adapted to receive theouter ends of the spring-actuated clamping-arms 13, by which means thedisk is held in place, the said arms being formed with notches 18,whichengage with one of the walls of the slots 17 and prevent the disk fromaccidentally slipping off the ends of the arms, the extreme outer endsof said arms being turned outwardly to form gripping-handles forreleasing the arms from engagement with the disk and nut.

From this description it will be seen that I have provided an attachingdevice for hubs which can be quickly put on and taken off and which willsecurely hold the hub in place, doing away with screw-threads and thenecessity of awrench. The device is adapted to turn with the wheeleither forward or backward without liability of coming off.

\Vhile I have shown and described the device in connection with anaxle-nut and axle, it isobvious that the same may be used on a nut andbolt, doing away with the threads on the same and providing the boltwith an annular groove and'the nut with holes for the reception of theends'of the clamping-arms, as herein described.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the construction, operation,and advantages of my improved hub-attaching device will be readilyapparent Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is i 1. In a device of the characterdescribed, the combination with an axle-spindle having an annulargroove, and a hub; of a nut having a smooth bore and adapted to slip onsaid spindle, holes formed in said nut, spring-controlled clam ping-armshaving an gularly-bent ends adapted to pass through said holes andengage said annular groove to hold said nut in place, and aspring-controlled bearingblock carried by said nut for taking up thewear upon the washer of said hub, substan tially as specified.

2. In a device of the character described, the combination with anaxle-spindle having an annular groove, and a hub; of a nut having asmooth bore and adapted to slip on said spindle, holes formed in saidnut, spring-controlled clamping-arms having angularly-bent ends adaptedto pass through said holes and engage said annular groove to hold saidnut in place, and a spring-controlled bearingblock carried by said nutfor taking up the wear upon the washer of said hub, and a dust cap orguard carried by said clamping-arms, substantially as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- IRA F. WOOD.
